QANTASLink Boeing 717-2K9 VH-NXH operated QF1898 Perth – Karratha this morning, however following the earlier Boeing 717-200 technical issue at Christmas Creek it then positioned Karratha – Christmas Creek as QF6200 in order to operate the delayed QF1975 Christmas Creek – Perth. As a result QF1899 Karratha – Perth was cancelled.
